Scientific Method Review 6th Grade Science

Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to several different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30 second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music. Which component is missing from Carmen’s experiment? A question A hypothesis A control group A description of the experiment

Some students are experimenting to test whether plants need fertilizer for growth. How should they treat the control plant in this experiment? Give it twice as much fertilizer Seal it in a clear glass jar with no fertilizer Do not give it any fertilizer Give it more than one brand of fertilizer

A scientist testing the affects of a chemical on apple yield sprays an orchard with the chemical. A second orchard does not receive the chemical. In the fall, the number of apples harvested from each forest is counted. Which of the following is the independent (manipulated) variable in the experiment? A) the chemical B) the number of apples C) the first orchard D) the second orchard

An experiment for a new asthma medication was set up into two groups An experiment for a new asthma medication was set up into two groups. Group one was given the new drug for asthma, while group 2 was given a sugar pill. The sugar pill serves as a ____________. A) control B) constant C) experimental variable D) dependent variable

A scientist plants two rows of corn for experimentation A scientist plants two rows of corn for experimentation. She puts fertilizer on row 1 but does not put fertilizer on row 2. Both rows receive the same amount of water and light intensity. She checks the growth of the corn over the course of 5 months. What is a constant in this experiment? A) Plant height B) Corn without fertilizer C) Corn with fertilizer D) Amount of water

The measurable factor in an experiment is known as the: A) control B) independent variable C) constant D) dependent variable

Mrs. Crain wanted to see how different types of music affected students' pulse rates. She played different types of music: heavy metal, rap, R&B, alternative, pop, country, and classical music. Identify the dependent variable. A) types of music B) high pulse rate C) pulse rate D) Mrs. Crain E) classical music resulted in the highest pulse rate

Mrs. Crain wanted to see how different types of music affected students' pulse rates. She played different types of music: heavy metal, rap, R&B, alternative, pop, country, and classical music. Identify the independent variable. A) types of music B) high pulse rate C) pulse rate D) Mrs. Crain E) classical music resulted in the highest pulse rate

Mrs. Crain wanted to see how different types of music affected students' pulse rates. She played different types of music: heavy metal, rap, R&B, alternative, pop, country, and classical music. What constant should be considered when doing this experiment? A) types of music B) amount of time the music was played C) using a different student for each music type D) use all dead people

Mario studied how far room temperature water would spurt out of a plastic milk carton when 3mm holes were punched at different heights from the bottom of the container. Identify the independent variable. A) 3 mm holes B) distance water traveled out of carton C) different heights of holes in container D) ice water from Iceland

Mario studied how far room temperature water would spurt out of a plastic milk carton when 3mm holes were punched at different heights from the bottom of the container. Identify the dependent variable. A) 3 mm holes B) distance water traveled out of carton C) different heights of holes in container D) rice water from Iceland

Tiffany was investing how fast it took Hayden to react to different sounds. Identify the independent variable. A) how fast Hayden reacted B) how much time it took Hayden to react C) playing the trumpet over and over D) different sounds E) Hayden

The first step of the scientific method involves: forming a hypothesis making observations performing an experiment predicting the result of an experiment
